Use stringr functions for consistent and readable string operations

* * *

Utilize stringr package functions for cleaner string manipulation in R

* * *

The following code demonstrates the use of stringr functions to perform string operations in a more readable and consistent manner:

< Good Code >

Load the stringr package

library(stringr)

Example string

text <- "Hello, World! How are you?"

Using stringr functions for string operations

1. Extract substring

substring <- str_sub(text, start = 1, end = 5)

2. Convert to uppercase

uppercase <- str_to_upper(text)

3. Count occurrences of a pattern

count <- str_count(text, pattern = "o")

4. Replace pattern

eplaced <- str_replace_all(text, pattern = "o", replacement = "0")

5. Split string

split_text <- str_split(text, pattern = " ")
